I am getting an error when I install Docker

Question

I've already installed the docker, it worked just fine.I am now trying to install the Centos operating system, but I get the error constantly. The error is below.

+ sh -c 'yum install -y -q docker-ce'

Transaction check error:

问题似乎是安装的版本docker-ce-cli是18.09.0.ce-1.1.beta1.el7，它比docker-ce您尝试安装的软件包版本新18.06.1.ce-3.el7。该docker-ce包装是没有准备。

docker-ce-cli在安装docker-ce软件包之前，您必须降级或删除。
